无痛口腔麻醉仪在拔牙术中的应用观察

目的评价临床拔牙患者应用STA计算机控制口腔无痛麻醉仪疼痛的程度。方法选择正畸牙和阻生智齿拔除术的患者100例,两侧分别应用STA计算机控制口腔无痛麻醉仪注射法和传统注射法行局部麻醉,患者自身和医师分别对麻药注射时疼痛及术中麻醉效果进行评价。结果实验组与对照组麻醉注射时疼痛值(VAS值)差异有统计学意义(t=-15.65,P<0.001);医师评价术中麻醉效果无统计学差异(P>0.05)。结论应用STA计算机控制口腔无痛麻醉仪注射时患者感觉无痛或只感觉轻微疼痛,可以达到很好的麻醉效果。

Application of Oral Painless Local Anesthesia Unit in Tooth Extraction

Objective To assess the pain intensity in clinical tooth extraction patients anesthetized using the computerized local painless anesthetic unit.Methods Totally 100 cases were selected.The local anaesthesia injection through using the computerized oral painless local anesthetic unit was compared with traditional local anesthesia method.The effect of anesthesia was evaluated with VAS value during and after injection.Results Statistical analysis indicated that the VAS value had significant difference between the experiment group and the control group(t=-15.65,P<0.001).The effect of anesthesia between two groups has no significant difference.Conclusion Good anesthetic effect could be attained by using the computerized local anesthetic unit,and patients feel a little or no pains.
